- Criterion RV-6 Dynascope: these introduced many of us to visual astronomy In January 2008 Company Seven acquired a used Criterion RV-6 Dynascope for our Museum Collection. This is a 6 inch f/8 equatorial reflecting telescope originally sold new in December 1962 and yet this one remains uncommonly complete and original with original sales invoice and some documentation. Our article describes this RV-6 acquired by Company Seven, the production RV-6 models as they were changed over the decades, some history of the Criterion Manufacturing Co. who made this telescope, and insights into the evolution and marketing of these types of instruments from the 1950's through the peak of the space program, and into the 1980's.
- Criterion RV-6 Dynascope Restoration Gallery When in January 2008 Company Seven acquired a used Criterion RV-6 Dynascope for our Museum Collection (see the article listed above) we deliberated about whether or not to disassemble, clean, strip, refinish the instrument to restore its appearance more to like new. When we learned about a collection of images taken by Mr. Tom McDonough who did this to his RV-6, we asked if he would permit Company Seven to create an article around his efforts and he was kind enough to give us permission to use his images in this article.
